Abstract:The proposed innovation is a two-actuator, singularity-free double pointing system which has a spherical geometry. It has potentially widespread application as the basis of a new generation of singularity-free manipulator wrists which will not generate coupled arm/wrist singularities. It will also… more
Abstract:THE ORTHODONTIC FORCES APPLIED TO THE DENTITION AND THE RESISTANCE THE PERIODONTICS OFFERS TO THESE FORCES CONTROL THE RESULTING TOOTH MOVEMENT. THE RATIONALE OF THIS RESEARCH IS TO PROVIDE THE ORTHODONTIST WITH THE CLINICAL INSTRUMENTATION WITH WHICH TO MEASURE THE FORCES AND COUPLES PRODUCED BY… more
Abstract:A NOVEL VISCOMETER DESIGN WHICH HAS THE CAPABILITY TO PROVIDE A DIRECT READING OF ON-SET OF CRITICAL SHEAR RATES AT WHICH HIGHLY FILLED MATERIALS START TO DECOMPOSE IS DISCUSSED. A DEVICE SIMILARY TO ONE PROPOSED IN THIS PROGRAM HAS ALREADY BEEN BUILT AND EFFECTIVELY USED AT OIL COMPANIES. THE… more
Abstract:MELTER-ISV SIMULATOR IS BEING DEVELOPED AS THE INDUSTRY-STANDARD COMPUTATIONAL MODEL FOR SIMULATING IN-SITU VITRIFICATION (ISV) PROCESSES THAT ARE CURRENTLY BEING CONSIDERED AS ALTERNATIVE REMEDIATION TECHNOLOGIES FOR HAZARDOUS-WASTE SITES. THE ADVANCED STATE-OF-THE-ART COMPUTATIONAL MODEL IS ABLE… more
Abstract:The title of the proposed Phase I project is "Megaprogramming for NASA's Unmanned Missions: Domain-Based Software Engineering". The objective of the Phase I activities is to develop a domain-based software engineering life cycle process consisting of an integrated, object-based domain-engineering… more
Abstract:Survival rates for medical trauma caused either in the military battlefield or at a civilian injury scene decrease dramatically if treatment is delayed for more than one hour. The ability to remotely sense and assess the severity of wounds would enhance support decisions to plan and manage overall… more
Abstract:POSITRON EMISSION TOMOGRAPHY (PET) IS A POWERFUL NEW TOOL FOR RADIOGRAPHIC IMAGING OF HUMAN ORGANS, PARTICULARLY THE BRAIN. HOWEVER, MOST PRESENTLY KNOWN SCINTILLATOR MATERIALS FIND THEIR APPLICATION LIMITED BY DEFICIENCIES IN ONE OR MORE OF THE DESIRED CHARACTERISTICS: BRIGHTNESS, STOPPING POWER,… more
Abstract:DETECTION OF WEAPONRY AND OTHER HAZARDS IS AN UNFORTUNATE BUT NECESSARY FACTOR IN MODERN TRANSPORTATION ENVIRONMENT. FOR INANIMATE OBJECTS, ONE PARTICULARLY ATTRACTIVE TECHNIQUE IS GAMMARAY DETECTION. IRRADIATION WITH A HIGH-ENERGY SOURCE, SUCH AS A NEUTRON EMITTER, CAUSES ELEMENTS IN THE OBJECT TO… more
Abstract:Since hybrid propulsion is being developed for space launch vehicles, there is a strong need for understanding the physical mechanisms causing hybrid rocket combustion instability. The project's objective is to develop and demonstrate a Liquid Oxygen Hybrid Motor Combustion Stability Test Bed. This… more
Abstract:Acute hepatic failure (AHF) with Stage 4 coma is a serious illness with over 60% mortality whentreated with supportive therapy. The BioLogic-DT is an extracorporeal liver support device in whichblood passes through cellulosic packages with a suspension of powdered charcoal and cation… more
Abstract:This proposal outlines the design and development of a uniflow two stroke Aero-Diesel engine core in response to the NASA SBIR solicitation for a general aviation aircraft propulsion system. The proposed engine will offer increased power density, simplified operation, reduced emissions, noise, and… more
Abstract:This proposed program will demonstrate the feasibility of a battleground IFF system in which neither the interrogator nor the responder need to transmit distinguishable electromagnetic signals which can act as beacons to enemy anti-radiation weapons. The system can operate in a fully double-passive… more
Abstract:The objective of the proposed research is to develop an integrated system for dynamic stress analysis of aircraft tires. The system will use the Projection-Moire concept, whereby a high-density line-set of Master Grating is projected on the investigated surface. The projected lines, deformed by the… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
